"Their cattle, if not very numerous, are at least very profitable. They are invisible as their owners are, unless when it pleases them to appear, which usually takes place when the weather is serene and the sun shining very bright; for as they do not see the sun within their dwellings, they frequently walk out in the sunshine that they may be cheered by his radiance.[220] Hence, even the coffins of dead kings and nobles, such as are the oblong stones which are to be seen here and there, in wildernesses and rough places, always lie in the open air and exposed to the sun. "They change their abodes and habitations occasionally like mankind; this they do on new-year's night; whence certain dreamers and mountebanks used on that night to watch in the roads, that, by the means of various forms of conjurations appointed for that purpose, they might extort from them as they passed along the knowledge of future events.[221] But people in general, who were not acquainted with such things, especially the heads of families, used on this evening strictly to charge their children and servants to be sure to be serious and modest in their actions and language, lest their invisible guests, and mayhap future neighbours, should be aggrieved or any way offended. Hence, when going to bed they did not shut the outer doors of their houses, nor even the door of the sitting-room, but having kindled a light, and laid out a table, they desired the invisible personages who had arrived, or were to arrive, to partake, if it was their pleasure, of the food that was laid out for them; and hoped that if it pleased them to dwell within the limits of their lands, they would live safe and sound, and be propitious to them. As this superstitious belief is extremely ancient, so it long continued in full vigour, and was held by some even within the memory of our fathers."[222] The Icelandic Neck, Kelpie, or Water-Spirit, is called Nickur, Ninnir, and Hnikur, one of the Eddaic names of Odin. He appears always in the form of a fine _apple-grey_ horse on the sea-shore; but he may be distinguished from ordinary horses by the circumstance of his hoofs being reversed. If any one is so foolish as to mount him, he gallops off, and plunges into the sea with his burden. He can, however, be caught in a particular manner, tamed, and made to work.[223] * * * * * The Icelanders have the same notions respecting the seals which we shall find in the Feroes and Shetland. It is a common opinion with them that King Pharaoh and his army were changed into these animals. FOOTNOTES: [218] This was plainly a theory of the monks. It greatly resembles the Rabbinical account of the origin of the Mazckeen, which the reader will meet in the sequel.
